Trying to copy pictures and video via PTP from a camera does not work any more.
Booting of an older Debian 8 is needed and there it works without problem.
Some pictures are maybe copied and then the copy goes into hold.
Afterwards a try to reconnect to the camera shows up error 150 (wrong parameter).
After camera is switched off and reconnected the same result occurs.
